The present invention provides a multi-functional printed circuit board (PCB) for assembling a plurality of components of a power converter in to a single package. The PCB comprises: one or more planar coils respectively formed on one or more PCB layers and aligned with each other for constructing the transformer and the coupler; and a plurality of conducting traces and vias for providing electrical connection among the plurality of components of the power converter.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The multi-functional printed circuit board (PCB) according to claim 3, further comprising a shielding layer interposed between the transformer layer assembly and the coupler layer assembly.
9. The multi-functional printed circuit board (PCB) according to claim 8, wherein the primary-side controller further comprises a primary band-pass filter configured to filter out noises from the synchronization signal which is to be transferred by the built-in coupler.
10. The multi-functional printed circuit board (PCB) according to claim 9, wherein the secondary-side controller comprises a secondary band-pass filter configured to filter out noises from the synchronization signal transferred by the built-in coupler.
11. The multi-functional printed circuit board (PCB) according to claim 10, wherein the secondary-side controller further comprises a demodulator configured to receive the synchronization signal filtered by the secondary band-pass filter and demodulate the synchronization signal to extract the primary control signal.
12. The multi-functional printed circuit board (PCB) according to claim 11, wherein the secondary-side controller further comprises a secondary driver configured to receive the extracted primary control signal and generate a secondary control signal for controlling the secondary switch based on the extracted primary control signal.
16. The method according to claim 15, further comprising interposing a shielding layer between the transformer layer assembly and the coupler layer assembly.
